SPRING-PAD CONSTRUCTION.

Application filed February 20, 1928. serial'li'o. 89,785.

This invention relates to spring padoonstruction, particularly springpads used in garment and laundry pressing machines and has for itsobject a spring pad which 1s 5 particularly simple and economical inconstruction, yielding in its action to conform ,to any inequalities asbuttons and the l1ke in the article being pressed and highly eili-'cient and durable in use.

The invention consists in the novel tea- ,tures and in the combinationsand constructions hereinafter set forth and claimed.

In describing this invention, reference 1s had to theaccompanyingdrawing in which .|5' like characters designate correspond ng parts inall the views.

Figure 1 is a plan-view, partly broken away, of a spring pad embodylngmy 1nvention.

Figure 2 is an edge view, partly in section, of parts seen in FigureFigure 3 is 'an end vlew left in Figure 1.

I This spring pad comprises, generally, up- 25 per and lower plates,coiled springs between the plates, a resilient abutment for receivingthe pressure and relievin the springs of the compression after they hvebeen compressed 'a predetermined amount, the s r1ngs being 3unattached to either the top or ttom plate and the abutment serving toholdthem 1n upright position and means enclosing the foregoing parts forholding them in assembled relation. Some ofthe foregomg features mayobviously be omitted.

1 and- 2,..are respectively the top and bot- "'tom plates j 3 areSprings inserted between the .plates and thrusting at their ends agalnst4 the plates.

4 is the yielding abutment for relieving the springs 3 of compressionwhen they have been compressed a' predetermined amount, this abutment 4being a base formed with holes 5 therein in which the springs 3 areseated, the lower ends of the springs thrusting against the bottom plateThe abutment 4 thus holds the springs in uprlght position as the springsare'not attached to either the top or the bottom plate. Thls abutment 4is preferably formed of matting or a sheet of felt with the holes 5punched therein. The top plate is also of felt or other porous materlalas well as the bottom plate 2. If desired, the base 4 and bottom lookingto the 'lower plates, a base member resting on the lower plate andformed 'withlholes therein plate 2 may be integral with each other.These parts as the top plates 1, 2. springs 3 and base 4 are held fromlateral displacement or in assembled position by a wrapper or casing 6shaped to fit them. This wrapper or casing 6 is in the form of a sackhaving upper and lower fiat sides 7 8 and an edge wall 9 in theform of aband of a width substantially equal to the height of the spring pad. .Inother ,words, the sack is made to fit the pad snugly.

The spring pad is here shown as tapered, andas having rounding ends andalso as open at its larger end for permitting the insides of the pad,that is, the top and bottom plates 1, 2,'springs 3 and base 4 to beinserted therein. The pad is held closed at its open end by a suitablecord 10.

The top and bottom plates 1, 2 as well as the sack or the top and bottomsides 7, 8thereof are of material of such porosity as to permit steam tobe passed therethrough.

In operation, when t e pad is placed on the lower buck of the pressingmachine and the head of the machine brought down on the garment thereon,the springs are compressed until their upper ends become even with theupper surface of the base 4 or until the top plate 1 comes down on thebase 4, the latter forming a spring pad to which the final heavypressure is applied. Also any portions of the top plate can yield andembed into the base 4. For instance,

buttons on a garment can be depressed into the to plate 1 and the base 4will yield or have ormed therein a corresponding depresslon.

L Owing to the construction, no means as rivets and the like arenecessary to hold the arts of the pad together but the parts of t e padcan be laid together and inserted in the sack.

What]: claim is: g t 1. "A- spring pad comprising upper and which holesconstitute sockets and coiled springs seated in the sockets and restingat their lower ends on the base plate, the springs projecting above thebase member, the top plate resting on the upper ends of. the springs. i2.'.A spring pad comprising upper and lower plates, a basemember restingon. the lower plate and formed with holes therein which} "holesconstitute sockets, coiled springs seated in the sockets and resting att eir lower ends on the base plate, the top plate resting on the up rends of the s rin and a wra er enc osin the lates, the wfi apper beingil i the form (if aflaii; sack open at one edge, base member and springsand holding, them in assembled relation.

3. A spring pad construction comprisin upper and lower plates, springsinterposed between the plates and a yielding abutment .with socket holesthroughout 1ts area, and

coiled springs seated in said holes, and ex tending beyond a face of theabutment plate, these holes being deep enough to enclose a plurality ofthe coils of each spring and :hold the spring in upright positionwithout interfering with .the compressing of such springs, the lowercoils of the springs being located 'within the holes walls of the holes.I

5. A spring ad comprising a base abutwhereby the springs are heldupright by the ment member 1n the form of a thick plate formed withholes throughout its area, and coiled springs seated in said holes andextending beyond a face of the abutment plate, the lower coils of thesprings being located within the holes whereby the springs are heldupright by the walls of the holes,

the abutment plate being of yielding material.

6. A spring pad comprising a matting of yielding material havingsocket'holes therein throughout its area, coiled springs seated 'in saidsocket holes and projectin out of the holes, and a wrapper for holingthe parts assembled, the wrapper being in the form of a flat sackentirely enclosing the top, bottom and edges of the matting with thesprings therein.

. In testimony whereof I have hereunto signed my name at Idavenport, in,the county of Scott, and State of Iowa, this 5th day of February, 1926.
